Landsat-5 bumper-mode geometric correction
IEEE Transactions on Geoscience and Remote Sensing, 2004The Landsat-5 Thematic Mapper (TM) scan mirror was switched from its primary operating mode to a backup mode in early 2002 in order to overcome internal synchronization problems arising from long-term wear of the scan mirror mechanism. The backup bumper mode of operation removes the constraints on scan start and stop angles enforced in the primary scan

Landsat-4/5 Band 6 relative radiometry
IEEE Transactions on Geoscience and Remote Sensing, 2002Relative radiometric responses for the thematic mapper (TM) band 6 data from Landsat-4 and Landsat-5 were analyzed, and an algorithm has been developed that significantly reduces the striping in Band 6 images due to detector mismatch. The TM internal calibration system as originally designed includes a DC restore circuit, which acts as a feedback ...

Irradiance-based cross-calibration of Landsat-5 and Landsat-7 Thematic Mapper sensors
International Journal of Remote Sensing, 2003On 2 June 1999 Landsat-5 and Landsat-7 passed over north-central Nebraska collecting Thematic Mapper (TM) data for essentially the same spatial location, with an acquisition time differing by less than 20 min. At the Niobrara Nature Preserve, Nebraska site, two multifilter rotating shadowband radiometers (MFRSRs), a Cimel sunphotometer, a Microtops ...

Landsat-4 and Landsat-5 thematic mapper band 6 historical performance and calibration
SPIE Proceedings, 2005Launched in 1982 and 1984 respectively, the Landsat-4 and -5 Thematic Mappers (TM) are the backbone of an extensive archive of moderate resolution Earth imagery. However, these sensors and their data products were not subjected to the type of intensive monitoring that has been part of the Landsat-7 system since its launch in 1999. With Landsat-4's 11

Revised Landsat-5 Thematic Mapper Radiometric Calibration
IEEE Geoscience and Remote Sensing Letters, 2007Effective April 2, 2007, the radiometric calibration of Landsat-5 (L5) Thematic Mapper (TM) data that are processed and distributed by the U.S. Geological Survey (USGS) Center for Earth Resources Observation and Science (EROS) will be updated. The lifetime gain model that was implemented on May 5, 2003, for the reflective bands (1-5, 7) will be ...

IEEE International Geoscience and Remote Sensing Symposium, 2003
The data from the Landsat program constitutes the longest record of the Earth's surface as seen from space. Landsat 1 was launched in 1972 with the Multi-Spectral Scanner sensor (MSS), which was specifically designed for land remote sensing. This sensor proved so valuable that it was used with four subsequent Landsat missions.

Improvement in absolute calibration accuracy of Landsat-5 TM with Landsat-7 ETM+ data
SPIE Proceedings, 2005The ability to detect and quantify changes in the Earth's environment depends on satellites sensors that can provide calibrated, consistent measurements of Earth's surface features through time. A critical step in this process is to put image data from subsequent generations of sensors onto a common radiometric scale.

Monitoring of a rice field using landsat-5 TM and landsat-7 ETM+ data
Advances in Space Research, 2003Abstract Through the research on the application of the multi temporal data acquired with Landsat-5 TM and Landsat-7 ETM+ to monitoring of rice field the following features are clarified Two vegetation indices NDVI (Normalized Difference Vegetation Index) and EVI (Extended Vegetation Index) obtained from Landsat-5 TM data of 7 July 2000 and that from

Landsat-5 Thematic Mapper cold focal plane characterization
International Journal of Remote Sensing, 2003The gain response of the detectors in the cold focal plane of Landsat-4 and Landsat-5 Thematic Mapper (TM) is known to fluctuate temporally. This is believed to be caused by an interference effect due to a film build-up on the cold focal plane dewar window. This paper analyses the effect using a thin-film interference model. This model relates detector

Landsat-5 Thematic Mapper Thermal Band Calibration Update
IEEE Geoscience and Remote Sensing Letters, 2007The Landsat-5 thematic mapper (TM) has been operational since 1984. For much of its life, the calibration of TM has been neglected, but recent efforts are attempting to monitor stability and absolute calibration. This letter focuses on the calibration of the TM thermal band from 1999 to the present.
